IMPROVEMENT IN OSCILLATING BERTHS FOR SHIPS.

Specification forming part of Letters Patent No. 140,014., dated June17, 1873; application iled A April 23, 1873.

To all whom it may concern:

Be it known that I, Isaac ANToiNE CHOMEL, of the city, county, and StateofN ew York, have invented certain new and useful Improvements inSuspended Ships7 Berths; and I do hereby declare the following to be afull, clear, and exact description of the invention, suchvas will enableothers skilled in the art to which it pertains to make and use it,reference being had to the accompanying drawings, which form part ofthis specification.

My invention relates generally to certain improvements upon the originaldevice for which I obtained Letters Patent, dated August 27, 1872 5 andconsists in modifications in the suspending apparatus by which theoscillations due to the motions ofthe vessels are reduced, andconsequently less space is required for the berth, while the free spaceover the berth itself is increased; and consists in suspending the berthby a universal joint upon the end of a fixed rod, bringing the point ofsuspension as low and as near the center of gravity as is practicable,and still allow the suspended berth to move in any direction under it.It also consists in combining with this c mode of suspension, a rigidsuspension frame attached to the berth and extending above the point ofsuspension, which yobviates the necessity of guy-rods, and, togetherwith the articulated frame, makes a more perfect suspension with lesshorizontal oscillations than has ever before been produced.

In the drawings, Figure I is a perspective view of the berth as hung inastate-room, and Figure II a detailed view of the point of suspension.

A represents the ceiling, deck, or bottom of an upper iixed berth, U thefloor, and B B sides of the cabin or state-room. a is a bolt irmly ixedto the ceiling and terminates at the bottom by a ball-and-socket orother universal joint, from which the berth is suspended. 'D is a singleberth supported by the stii suspension frame d1 d1 Iirmly attached toits head and foot. Said frame extends above the'universal` joint, and isconnected with it by arms d? d2, thus allowing more space Athe view ofthe sides ofthe cabin, contribute materially to remove one of the maincauses of sea-sickness. To the bottom ofthe berth or platform isfastened a projecting ro-d, cl3,

the lower end of which passes through a hole in the lower bar F of lthearticulated frame, and replaces, in some cases, the guide-bar describedin my original said patent. rIhe berth`can, of course, be so constructedas to be transformed into a chair 5 or it may be replaced by a platformto be occupied by passengers, or goods such as glass-ware or crockery,&c;or a whole cabin can be suspended in the same manner. d4 is ahorizontal double bolt worked by an eccentric or link motion produced bya vertical lever, d5, and which, when extended, enters the sides of thecabin or grooves made therein, and keeps the bed stationary untilreleased at the will of the occupant of the berth. The articulated frameE E and F, having its three limbs hinged at c e, instead of hanging fromthe ceiling, is suspended from the sides of the cabin at e', c', atpoints nearly on a level with the point of suspension a2 of the berth.This' disposition diminishes the horizontal oscillations of the bed andsaves space. Gr is a spiral spring attached to the ceiling'or sides ofthe cabin, and to the suspension frame, to counterbalance, to someextent, the unequal weight of the occupant of the berth, and check thetoo free oscillation of the apparatus.

What I claim as my invention is- 1. rlhe single bolt al, with its lowerend a2, forming a universal point of suspension lower than the ceiling,and as low and as near the center of gravity as is practicable, incombination with a berth constructed and operating substantially as andfor the purpose herein described.

oscillations by an articulated frame, substantially as desoribed.

1n testimony that I claim the foregoing I have hereunto set my hand this18th day of April, 1873.
